“What does it feel like?” My sister had asked me one Saturday morning as we sat upon my bed. She is a sweet, curious creature who longs to know everything about everything, and especially everything about me. We were close growing up, Anna and I, even though she is three years my junior. She possesses an imagination that conjures all manner of innocent fantasies and games, and our youth had been such a joyful experience that our parents determined that we should never be far apart. How little we all knew then. There are a great many things that occur during the passage of youth that form the foundation of our adult lives. From even the moment of conception, the world around us influences everything we become. The influence of family provides the strongest of impressions upon our minds and upon our hearts. Indeed, it is from the relationships of our closest family that we learn of love, and from their example we base all our hopes and dreams for our own happiness. Some, it must be said however, are far more privileged in the article of family than others.

But life is not as simple, and certainly not as care free as we perceive it to be in childhood. The idealistic image of perfection we assume our families to be, rarely proves to be accurate, and it is through the understanding of the true nature of our surroundings that our innocence is lost. My own innocence was lost a year or so past when I discovered that my mother was having an affair. It had been quite a shock to catch them in the act, to see my naked mother engaged in sexual intercourse with a man that was not my father. I remember the ample curves of her body bouncing freely as she writhed upon that stranger’s considerable cock, while his hands grasped about her breasts. For his part, my father had not responded well to my mother’s infidelity, having discovered that shocking scene in the same moment as I. He had packed a bag and left that night, and our family life has changed considerably since.

This was not my first experience of sex, not by any means, for my parents had not been overly careful in concealing their copulation. The first time I had seen them was when we were mere kids, being dragged by my sister to our parents’ bedroom doorway to watch them having sex. At that age, my sister had declared the whole thing disgusting, and I could only agree. Our views have of course changed dramatically since then, and my virginity was freely given when I was fifteen. I am seventeen now, while my girlfriend Amy is almost a year older, and I would consider having sex with her to be the best part of our relationship. Fortunately, she enjoys having sex with me as much as I do, and we try to make the most of every opportunity that presented its self. I could go so far as to say that we both have quite a high sex drive. My sister meanwhile had not experienced sex first hand herself prior to that particular Saturday. In fact Anna’s knowledge of it was limited only to what she had been told at school, and from what little I had told her.

So it was on that November morning last year when we were sitting upon my bed that Anna presented her question. It was not unusual for my sister to be there in the mornings, especially now that my father had moved out, and when our mother was at work it fell to me to look after Anna. She and Amy had become the very best of friends, Amy being akin to the big sister that Anna had always wanted, and they delighted in makeovers, nail painting, and of course talking about boys. That morning however, had quite uncontrollably departed from what might be considered normal, when my sister had burst into my bedroom waving a letter in her had. The letter was not of consequence, but it was the article that had prompted her to enter my room, and in doing so Anna was presented with her first real view of my naked body. This might not have been so bad, of course, had my body not been intimately joined with that of my girlfriend. Amy lay beneath me, attempting to muffle her moans with the back of her hand as my penis pushed into her again and again.

Interrupted mid thrust by the sound of my bedroom door opening, the shrill, incomprehensible voice of my excited sister and then her sudden gasp as she clapped eyes on us, was enough for Amy to put an end to our fun. Anna just stood there staring, her open mouth hung uncontrollably for a long moment until I was able to sit back and compose myself, more than a little annoyed at the timing of the interruption, for I was close to reaching an orgasm. It was at that point Anna dropped the letter and ran out of the bedroom, and she could be heard crying as she ran down the corridor. I was not sure what to make of it all, for I had never been caught in the act before, and as Amy slipped from the bed and wrapped her long white bathrobe around her, I wondered just how much my sister had seen. There had been occasions in the few months previous when Anna had nearly walked in on us, but I had always tried to be careful. Amy was of the opinion that it didn’t matter if Anna saw us, but I had been determined not to expose my sister to anything resembling the view I saw of my mother. But it was too late now.

Amy went after my sister, while I pulled on my own robe to cover myself, and when she came back a few moments later she was holding Anna’s hand. The tears had been wiped from her eyes, but Anna looked solemn and shy.

“Don’t worry about it.” I told her, hoping that would be the end of it, but the look on Amy’s face suggested more needed to be said. “It’s fine. Just knock next time okay.” I said, and gave Anna a smile to prove I wasn’t upset with her. My sister was a cute girl, slim and short for her age with long brown hair that stopped about half way down her back. She was wearing her normal white night dress which had a ribbon at the top beneath her chin and it hung loosely around her knees. She frowned and looked up at Amy who sighed.

“I said she could watch.” Amy said at last, and gave my sister a reassuring smile of her own. Amy by contrast had blonde hair, but it was long like my sister’s and they had much the same build and complexion, just a few years older and with a beautiful pair of breasts.

“Watch what? You don’t mean…?” I was stunned. Of the two of us, Amy was the sensible one, but I had no notion that she could think I might allow my sister to watch us having sex. But Amy nodded and smiled again.

“She’s curious. You know what she is like.” Amy replied. “She wants to know what happens, she is full of questions and don’t see any harm in letting her watch.”

“I don’t know.” I said cautiously. It was normally I who suggested experimenting and trying new things during sex, but this felt like crossing some sort of invisible line. “I don’t think it is a good idea. Besides, she’s my little sister!” Anna frowned.

“What does that matter?” Amy shot back. “She’s not a kid anymore and it would be better for her if she learns from us rather than from some kid who doesn’t know what to do.” Anna nodded hopefully by her side and Amy seemed determined to get her way. But I was not prepared to give in and let my own sister watch us have sex. I was not even sure if I was comfortable having sex in front of someone else, anyone else, and even if I was I was certain that my sister would not have been my first choice. But I knew that both my gorgeous girlfriend and my sweet little sister could be very persuasive when they wanted to be with their wide, adorable eyes and so I looked for a way out of it.

“It’s not a good idea.” I repeated, “What if Mum finds out?” Anna looked even more disappointed than before, but an idea formed in my mind that seemed like a good compromise. “Perhaps we could just talk about it and answer some of her questions?” Amy looked at Anna who smiled, and for a moment I felt like the compromise had succeeded. Amy invited my sister to sit on the bed and then excused herself, heading in the direction of the bathroom. Suddenly I felt very nervous about sitting on the same bed as my sister. Anna crossed her legs and the moment she believed I was ready she blurted out her first question.

“What does it feel like?” She asked. “Sex, I mean.” For a moment I looked at my sister blankly, scrambling through my mind in search of something appropriate to say and failing miserably.

“I don’t know really,” Were the words that came out at last. “It is hard to explain… it feels…”

“It feels amazing.” Amy declared as she returned to the room and bounced onto the bed. “It’s the best thing in the world.” I could do nothing but agree, for I certainly thought so, but I was quickly discovering that talking about it was not something I was particularly comfortable with. “When your brother puts his shaft inside me, I get the most wonderful feelings.”

“Penis!” I added, smiling at my girlfriend to cover my embarrassment. Anna blushed at the blunt use of the word, but Amy seemed to be having fun. Perhaps she found some perverse enjoyment from making me uncomfortable. It was certainly a side of my girlfriend that I had not seen before in the fifteen or more months we had been together.

“Is it very big?” My sister asked from behind wide, irresistible eyes. It was the sort of look which told me that she was taking in everything with an eager desire to learn. I had seen it many times in the past, when my sister had been fascinated, quite transfixed upon something, and it was almost always something that involved me.

“Yes it is. At least, I think it is.” Amy said grinning proudly. “Perhaps you could tell us what you think of it.” She suggested, and I could not believe what Amy done next. One moment I was sat there in all modesty, covered by my bathrobe, and the next Amy had pulled the sides apart so that my entire waist was on display. Anna could see everything, her wide eyes staring right between my legs as I sat there in shock. It was only for an instant though, and I was able to pull at least half the robe back and cover myself before glaring at my girlfriend in disbelief, who was laughing.

“What the… Why did you do that?” I exclaimed as I crawled to my knees to cover up properly. “You just let my sister see my… well, everything.”

“Don’t be a spoil sport.” Amy laughed. “It’s not as if she hasn’t seen it before. I’m sure she had a good look earlier.” Anna nodded. “See… So come on, give Anna a proper look.”

“But, she’s my sister.” I protested again. “It’s not right that she should see me like…”

“Naked? Why not,” Amy asked playfully. “Didn’t you tell me that it was natural to be naked? I remember you going on about it when we first got together. Something about clothes being oppressive and unnatural I think you said.”

“Yes, well. I said that because I wanted to see you naked.” I replied, trying to find a way I could get out of the predicament with my dignity. Amy laughed and stood up from the bed.

“Exactly, and now she wants to see you naked.” Amy sighed. “Alright, I will make it easy for you.” She said, and with that she untied her bathrobe, slipped it off her shoulders and allowed it to fall lovingly around her feet. Anna smiled as she gazed upon Amy’s beautiful naked body, and for a moment Amy stood there, allowing my sister to take everything in as my jaw dropped. “Right. Your turn.” She said.

“But…” I started my protest again.

“Not you. It’s Anna’s turn.” Amy smiled at my sister, who was still sat cross-legged on the other end of the bed. “Go ahead. Show your brother what he has been missing.” Anna didn’t waste a second. She jumped onto the floor, tugged at the ribbon around her neck and pulled the nightdress off in one swift motion. My sister stood beside the bed in nothing but a pair of white cotton panties. My eyes fixed upon her bare chest, for she was not wearing a bra, and for a long moment, I could not believe what I was seeing. Anna possessed the sweetest little breasts I had ever seen, so pert and pure with not a line or mark visible anywhere on her perfectly smooth skin. So beautiful she looked as she stood there in front of me that I barely noticed as she removed her panties and sat back down on the bed. “I think he likes what he sees.” Amy laughed, and the two girls giggled together. “Alright, now it’s your turn.” I felt a sharp poke in my side, dragging my mind back to the present and she repeated that it was my turn. Suddenly I realized, Anna was naked and I was just staring at her. All my resistance faded, I had no more arguments to make.

“Ok, alright.” I knelt up, untied my robe and threw it on the floor. The girls were grinning excitedly, and as I sat back on the bed I got the impression that my sister had been hoping for this moment for quite some time. “So, what do you think?” I asked.

“Well…” Anna replied thoughtfully. “It’s not very hard.” She had wanted to see my penis fully erect, and was actually disappointed that it wasn’t.

“Don’t worry. It will get there.” Amy reassured her. “See, it’s swelling up nicely already. Why don’t you help him out?”

“What?” Anna asked, wondering what Amy had meant. I might have been curious as well, had I not just spotted that my sister was no longer wearing her panties either. The way she was sitting with her legs crossed had given me an unbelievable view between them. The small slit between her plump labia was stretched open, and I could see Anna’s clitoris and the pink flesh of her vagina with vivid clarity. She was beautifully neat, with only a small patch of hair on her pubic region and almost none around the labia.

“Give him a hand.” Amy said encouragingly, emphasizing what she meant by creating a loose fist with one hand and shaking it. Anna didn’t need to be told twice, for she understood instantly what that gesture meant. She leant forward and crawled up the bed until she was right over me. I was about to say something to stop her, when Amy pulled my head around and gave me a passionate kiss. I felt my sister’s fingers as they wrapped around my semi erection, and my mind began to swim in sea of hormones and emotions.

“It’s getting harder.” Anna cried with pure joy as she felt me swell within her grasp. I knew I shouldn’t, but I was actually enjoying it. There was a pressure on my calves, which I realized, was my sister sitting upon them. I reached out to hold her with my free hand, the one not wrapped around my girlfriend, and when the kiss broke I looked at them both. Anna’s fingers played over and around the head of my penis causing pleasure with each movement, while Amy looked entirely pleased with herself.

“What do you think of your sister?” Amy asked. “Isn’t she beautiful?”

“Yes, she is… very… I… you… I mean” I stuttered, struggling to find the right words. Words that could not be taken the wrong way by either of them, so that they might at least sound like the compliment I intended. “You both are.” I wondered what would have happened if I had simply agreed to let Anna watch in the first place. Would things have gone differently, or was this always destined to happen.

“She has wonderful tits, don’t you think?” Amy said, and when I didn’t reply, she grabbed my hand and placed it onto Anna’s right breast. “There. Her skin is so soft. Go on, feel it.” I squeezed it cautiously, feeling suddenly very self-conscious as though alerted to there being some kind of trap. “No, no. Not like that, rub her nipples like mine, like I showed you.” Amy said sternly. Amy likes me to touch her breasts in a certain way, and had given me plenty of instruction on the correct way to do it after the first time we had been together. But touching my sister in that way didn’t feel right to me.

“No. I shouldn’t.” I protested, pulling my hand away and feeling quite guilty. “I can’t. She’s my sister. Its… it…” I wasn’t even bothered about Anna’s age, for I knew my sister was old enough to know what she wanted. I certainly did when I was her age. But she was my sister, and deep down I believed it was wrong.

“Incest?” Amy smiled at me. “Yes of course it is, and it’s perfectly normal. You two are lucky. I wish I had a brother to do this with, and my father is gone, so…” She trailed off. Amy’s father had died a few years ago, and I knew that it still upset her to think of him. “But Anna wants to be with you, so you should make the most of it.” My sister nodded and giggled in confirmation.

“But… What about you and me?” I asked, stunned once more by what I was hearing. “I’m with you. You are my girlfriend, Amy. I want to be with you…” She laughed.

“I’m not breaking up with you, silly.” Amy said, full of mirth at my sudden display of loyalty. “I want Anna to join us, and then we can all play together.”

“Please.” Anna pleaded. “I love you.” A sentiment emphasized by her fingers squeezing harder around my penis. She still had hold of it and was already massaging its shaft with far more zeal than when she had started. My sister looked so cute sat there, and there was no denying that I was attracted to her now. It was as though I was seeing her for the very first time, seeing the beautiful young woman she was becoming. My thoughts and feelings were more than a little confused, infused by the cocktail of hormones in my blood stream, and the throbbing sensation in my penis was becoming unbearable. I had never been so hard, so aroused by a girl than I was at that moment by my own sister. I was flattered, amazed and more than a little tempted by the idea, but it was the combination of wide-eyed hopeful looks from both girls that overwhelmed my moral objections. I was outnumbered and I realized that I really had no chance of escaping without upsetting one or both of them, and to my surprise I found that I was quite unable to resist.

“Oh, alright, I’m in. But we can’t let Mum find out.” I gave in, but part of me still felt as though it was a really bad idea.

“At last, well go on then.” Amy grinned. “Give Anna a kiss.” I done as I was told, lifting my sister up so that I was able to push my lips against hers. Her arms wrapped lovingly around my neck and I pulled her closer until I could feel her breasts brushing against my chest. Her lips tasted so sweet, and I allowed myself to enjoy the moment as they parted and she licked my lips. I was not just kissing her now, but she was kissing me, and I responded in kind. Our tongues met, pulled back and then met again. Only part of me registered the hand that had a hold on my erection, and not even that part comprehended what Amy was doing with it until I felt a warm, moist pressure settle upon its head. As soon as I had begun kissing my sister, my girlfriend had sought to set up the next step in my path to incest. There was no doubt that Anna could feel my stiff, throbbing cock pushing up between her labia, exactly where Amy had guided it. Ever so gradually I felt Anna pull back, putting more pressure on it until quite suddenly she slipped.

It was as though I had punched through a wall, and found a narrow space on the other side. Anna was very tight around my cock, and I knew in an instant what had happened. Her hymen had parted and I was really, actually having sexual intercourse with my own sweet little sister. It had not been intentional on my part, nor was I sure that I should have been doing it, but I had agreed to it and somehow I realized in that moment that it was what I wanted. I wanted to have sex with my sister, and knowing that Amy was there too only made the pleasure I felt more intense. Anna had pulled back from our kiss the moment I had penetrated her, and she was trying to hide the pain it had caused. She smiled up at me and told me again that she loved me.

“I love you too, sis.” I said, and then to Amy I smiled. “I love you both.” My girlfriend grinned sheepishly like a Cheshire cat, kissed me once on the lips and then quite to my amazement, she turned and kissed Anna too. I saw my sister’s eyes widen a little, but she didn’t seem to mind and returned the kiss with just as much affection. By the time Amy had moved away, I was so aroused that I had decided simply being inside my sister was not enough. Being careful not to let my cock slip out of her, I pulled my sister close again and then rolled her over onto the bed. The move was well executed and I positioned myself above Anna supported by my elbows on the bed either side of her head.

“That’s more like it.” Amy practically cheered, as my sister looked up at me with the most affectionate display of utter delight that I had ever seen. Keeping my eyes fixed upon my sister, I started to work my penis further into her. She was so tight that I could feel her flesh on every part of my penis, muscles squeezing against it, and it felt wonderful. Now that I was inside her, I was at a loss to justify why I had resisted for so long. It seemed senseless that I had so nearly denied myself such an amazing thing. It wasn’t just the act of having sex that made it feel so good, for I could do that with Amy at any time, and it wasn’t that Anna had been a virgin either. It felt the way it did because I knew I shouldn’t be doing it. She was my sister, my own little sister, and I was engaged in hot, passionate sex with her right there on my bed. More than that though, I was having sex with Anna right in front of my girlfriend. I was thrusting harder and deeper into my sister’s vagina with each passing moment, conscious that Amy was in the same room, and sat indeed upon the same bed. Surely, I pondered, this could not be considered cheating. After all, it was Amy’s idea, and she had wanted me to do it. She was sat there watching, enthralled by all she saw and was even giving comments.

“That’s good Anna.” Amy said softly. “Hold his back, and now dig your nails in. He likes that a lot.” She was right, I did like it, but at that moment the pleasure it caused was too much to handle. The moment her nails pushed into my back, I realized that it was too late. I had been holding back the urge to climax since we had rolled over, and I was almost ashamed that I should finish so quickly, but there was no stopping it. Semen erupted from my penis, forcing my teeth to grit as I tried desperately to maintain an even look upon my face. My warm cum flowed into Anna in three or four consecutive thrusts, and my sister moaned aloud as she felt it inside her. But it was all too soon, and I was so embarrassed that I couldn’t bring myself to admit that I had finished. So with a concerted effort, I carried on as best I could.

I have to say that for a guy it is rather difficult to continue having sex after an orgasm. The whole experience drains every ounce of energy out of the body, making it almost painful to keep going. Fortunately, having cum so quickly, I had not expended as much energy as I usually would have during sex, and for a long moment I was able to regain a rhythm. That was until I leant over to see what Amy was doing. I was not in the slightest bit surprised at what I saw, for Amy was sprawled out on the other end of the bed, her legs spread wide and her fingers were massaging her clitoris. She grinned back at me as she realized that I had seen her.

“Have you cum yet?” Amy asked, mockingly.

“Not yet.” I lied. I was panting in short, rapid breaths, feeling suddenly tired by the exertion. My arms and legs were beginning to ache and I wasn’t sure how much longer I could keep going, but I pushed on anyway. I was certain that I would not be able to cum a second time without resting for a while. I had only managed to do it a couple of times with Amy, and even then it had taken a long time and a lot of effort. I wasn’t sure I could manage it, even for my sister. Then again, I figured that it was probably for the best as I realized that neither of us had any form of contraception between us. “Actually, I don’t think I should.” I said to Amy. It is strange how such rational thoughts only come to mind after it is too late. “I don’t want to get her preg…”

“Oh, hurry up and cum already.” Amy replied, cutting me off. “It’s her first time, and she wants to know what it feels like. Besides, I can’t wait to lick your cum out of her pussy.”

“Are you ok?” I asked my sister, looking into her eyes. She nodded and I could see that she was enjoying the experience as much as I was. Her heart was racing and was trying not to moan aloud again.

“Are you going to cum in me?” Anna asked hopefully. I smiled at her, for I understood her desire, and I leant forward to speak into her ear.

“I already have.” I whispered as loud as I dared, and then sensing that Anna might say something to give me away, I kissed her, covering her mouth with mine. It wasn’t a long kiss, but it was passionate enough to have the desired effect, and it gave me an idea. If my sister wanted to know what sex felt like, I was certain that I could give her an orgasm too. With practiced ease, I pulled myself back into what was effectively a kneeling position, and using her legs I pulled Anna toward me. I liked this position more than any other, because it gave me a great view of her body and I was still in control. Furthermore, I could see the base of my penis protruding from her, moving steadily in and out as I shifted my hips back and forth. Looking down at her, I brushed my hand over one of her tiny rounded breasts, and then the other, caressing each puffy nipple in turn. Then with a gentle stroke over her belly, I ran my hand down until my thumb slid between her labia.

“Oh.” My sister cried as I touched upon the sensitive tip of her clitoris and began to brush my thumb over and around it.

“Does that feel good?” I asked, already knowing the answer, but I was still pleased when she nodded, while behind me, Amy was stating how much she loved it when I touched her like that. It was good for me too, really good in fact, and to my amazement I found that I was building toward another orgasm.

“Oh!” Anna cried again, and suddenly her chest rose and her head rolled back. I felt her tense up around my penis and her thighs pressed against mine. She grabbed my arm with one hand as she writhed under a wave of pure ecstasy. But I could not stop, not when I was so close to a second orgasm of my own. I thrust my cock into her harder, and again, while still rubbing my thumb around her clit. She squirmed, forcing me to hold her in place and she sunk back into the pillows, and then it happened. My own body tensed, as it had done so many times before with Amy, and I felt the semen building up inside. But this was no ordinary orgasm, for I had already cum once. This time it was far more intense, and in a way it was almost painful. Semen burst from me in a great explosion, causing relief as much as anything as it passed into my sister.

“Oh.” She cried out again. “Oh my… Oh!” She squirmed again, and lifted her hips so that my cock slid free from her, and her chest was pushed up once more. For a moment I tried in vain to get my penis back inside her, but all I managed to achieve was to spread cum around her labia. Some of which got under my thumb, and I massaged it into her clit as she continued to wriggle beneath me.

“Oh.” My sister moaned once more. “No, stop. Please stop.” She begged. Anna’s rigid body clung to the bed, and for a moment she could hardly move. I felt the presence of Amy looking over my shoulder and so I stopped.

“Wow. Did you enjoy that?” Amy asked, wrapping her arm around my waist. “How does it feel to be the one to take your sister’s virginity?” I didn’t answer, my entire focus was held captivated by my little sister as I watched her recover from her first real orgasm. When at last she lifted her head, Anna was grinning broadly from ear to ear. I flopped bodily onto the bed next to her, propping myself up on one side. With me out of the way, my girlfriend was back in control, and she moved with utter confidence. Her hand slid between Anna’s legs, and came back with a copious amount of my semen on her fingers. She licked them clean, and then bent between Anna’s legs, where she proceeded to lick all around my sister’s crotch.

“Was that alright?” I asked my sister. She nodded, still grinning uncontrollably.

We stayed in bed for most of that day, playing with each other and making each other cum. It really does feel fantastic to have sex, and both my girlfriend and my sister are amazing. But to have them both together has been the greatest thing in the world for me. Six months on, and the three of us still get together as often as possible. I have even started having sex with Anna when Amy is not around, and although I know I shouldn’t say it, I really think incest with my sister is better than having sex with Amy. Except of course, when I get to have both!
